What is the precursor of lung cancer

summary

My friend's father is a business owner, especially rich, but he often needs to go out to socialize, drink and smoke. That's a common thing. But some time ago, I called a friend and he said his father had lung cancer. Next, I'll give you a popular science about the precursor of lung cancer.

What is the precursor of lung cancer

First: because of the environmental pollution caused by smoking and burning coal, the incidence rate and mortality of lung cancer in various countries have increased sharply in recent decades. The same is true in China. In view of the high mortality of lung cancer, the average 5-year survival rate is less than 10%. Therefore, early detection of lung cancer and comprehensive treatment based on surgery are the key to improve the 5-year survival rate.

Second, lung cancer originated from bronchial mucosa epithelium, and those confined to the basement membrane are called carcinoma in situ, which can grow into the bronchi or / and adjacent lung tissue, and can spread through lymphatic blood or bronchial metastasis. The growth rate, metastasis and spread of cancer are related to the histological type, differentiation degree and other biological characteristics of cancer. Lung cancer occurs in bronchial mucosa epithelium, also known as bronchial lung cancer.

Third: fever, central lung cancer growth in the bronchus, to the lumen half or total obstruction, can produce obstructive pneumonia. Fever is generally around 38 ℃, and it is easy to reduce fever after anti-inflammatory treatment. But if the obstruction is not removed, the pneumonia will reappear soon, forming recurrent pneumonia.

matters needing attention

There are many early symptoms of lung cancer, such as fever, hemoptysis, cough, and some patients have no symptoms. If you find anything abnormal, you must check it in time, and don't wait for it to be serious before you start to pay attention, so it's too late.
